Said asked: How then can history tell that the end is reached right now, at that point X?

Pinpointing the exact day, of course, is not possible. But putting the probabilities in favor of a certain outcome, is very doable. In fact, it is exactly the total focus of my research. On December 1st, 2021 the Forbes List was released: www.forbes.com/sites/sergeiklebnikov/2021/12/01/heres-what-wall-streets-biggest-banks-predict-for-stocks-in-2022-and-what-to-watch-for/

These were Wall Street's predictions, and at the bottom what my perspective article stated, which was released on 1/1/2022.

In fact, the S&P 500's highest high was $4,818.62 on 1/4/2022. It's lowest low was on 10/13/2022 at $3,491.58. That is a drop of -27.54%. Now let me illustrate one example of how historical precedent helps. In the article I released on 1/1/2022 I shared research regarding inflation rates hitting six percent. Here is the table:

So this average from 1900 to the end of 2021 was -27.55%. The maximum drop in the S&P 500 was -27.54%. It was off by 0.01%. Will this ever happen again? Doubtful. But it illustrates how historical precedent can guide investments. It is not a crystal ball, but history often rhymes.

Keep in mind this is just one example. I track a very large number of indicators from various fields, and it is their consensus that I pay most attention to, not one single indicator in isolation.
